System.TypeInitializationException à l'affichage d'un calendrier dans un TabControl

Hello !

J'ai un gros problème avec mon application. J'ai crée un calendrier. Il s'affiche parfaitement quand j'utilise un Form. Par contre j'ai une erreur que je n'arrive pas à résoudre si j'utilise ce calendrier dans un TabControl. Le code est pourtant identique...

Voilà le détail complet de l'erreur:
